Calcium Tartrate (E354) is a Calcium Salt of Tartaric Acid considered to be a natural compound that is commonly used in food as a sequestrant, stabilizer, and leavening agent.

Metatartaric Acid (E353) is a natural acid derived from Tartaric Acid and is primarily used as an acidity regulator, anti-crystallization agent, and stabilizer.

Calcium Malate or E352 is an organic acid salt (Calcium Salt of Malic Acid) that is composed of a divalent cation of Calcium and Malic Acid and is used in food primarily as a flavor enhancer and buffering agent.

Potassium Malate or E351 is a Potassium Salt of Malic Acid in food primarily used as an acidity regulator and a buffering agent which presents itself as a white crystalline powder that has a slightly acidic taste but no smell.

Sodium Malate or E350 is a Sodium Salt of Malic Acid, in other words, a combination of two naturally found substances (Malic Acid and Sodium) that in food and supplements gets used primarily as an acidity regulator that presents itself as a white or off-white crystalline powder with no smell and slightly acidic or tart taste.

Magnesium Phosphate or E343 is a Magnesium salt of phosphoric acid that is used in supplements both as an additive primarily fulfilling the role of an acidity regulator or firming agent and the beneficial ingredient.

Calcium Phosphate or E341 is a Calcium salt of phosphoric acid that has a wide variety of different applications in food, supplements, and medicine while displaying no smell or taste and presenting itself either as a white crystalline powder or white granular powder.

Potassium Phosphate or E340 is a potassium salt of phosphoric acid that gets used in food primarily as an acidity regulator, stabilizer, and emulsifier and that presents itself as a white crystalline powder with no smell and slightly salty taste.

Sodium Phosphate (E339) is a Sodium Salt of Phosphoric Acid that is odorless, has a slightly alkaline taste, and presents itself as a white crystalline powder in food and supplements most typically used as an emulsifier, acidity regulator, and thickener.

Phosphoric Acid (E338) is a mineral acid (inorganic acid) that has no smell or color but is highly water soluble and has a sour and acidic taste. In food and supplements, it is primarily used as an acidity regulator and flavor enhancer.

Sodium Potassium Tartrate or E337 is a Tartaric Acid Potassium Sodium Salt that is basically a fusion of Sodium Tartrate (E335) and Potassium Tartrate (E336) that presents itself as a white crystalline powder with a slightly acidic taste and sometimes slightly acidic or sour smell.

Potassium Tartrate or E336 is a Potassium Salt of Tartaric Acid that presents itself as a fine, white crystalline powder (with often needle-shaped or elongated crystals) that is odorless and has a slightly acidic taste, and is primarily used as a leavening agent in food.
